SYRBNGEQNOZZLE.

SPECIFICATION forming part of Letters Patent No. 688,881, dated December17, 19101. Application tlled March 15, 1901. Serial No. 51,224. (Nomodel.)

To @ZZ whom t may concern:

Be it known that I, RUSSELL PAEKEE,a citi-V zen of the United States,residing in the borough of Brooklyn, city of New York, county of Kings,State of New York, have invented certain new and useful Improvements inSyringe- Nozzles, of which the following is a specifi-V cation.

My invention relates to vaginal irrigators; and it has for its object toproduce a syringenozzle particularlyadapted for use as a vaginalirrigator Which will thoroughly and efficiently cleanse the parts, whichwill be sanitary in use, and which may be readily cleansed andantiseptized.

In the accompanying drawings I have shown, by way of example, a vaginalirrigator in which one form of my invention is embodied.

In the drawings, Figure l is a longitudinal section through theirrigator on line 1 l of Fig. 2. Fig. 2 is a section above the elasticpartition on line 2 2 of Fig. 1, and Fig. 3 is a fragmentary sectionalview showing the position of the parts in use and the form assumed bythe spray.

In the drawings, a represents the tubular body, which may be made of anysuitable material, preferably hard or soft rubber. This body terminatesin a cup-shaped or conical seat l). Firmly seated in the bore c of thebody is a cross-piece, spider, or partition d. In the present instance Ihave shown it as a partition perforated centrally for the reception ofthe stem f of a spreader or button e and provided with a series ofapertures g, surrounding the said stem. This cross-piece, partition, ordiaphragm, Whatever its character, is made of a highlyelastic substance,such as pure rubber, so that it may dilate or bend outwardly, as shownin Fig. 3. In the present instance I have shown the spreader c as in theform of a button, round upon its external face 71, and tapering orfrusto-conical upon its inner face t' to snugly t the cup or recesswhich constitutes the conical seat b. The stem f is provided with asuitable head j, which forms a shoulder to engage behind the diaphragmd. The

exterior surface h of lthe spreader preferably forms a practicalcontinuation of the outer wall of the tubular body a, so that the end ofthe irrigator will form a practically continu-v ous surface withoutpresenting crevices for the lodgement of foreign matter. The parts arepreferably so constructed that normallythat is to say, when thediaphragmd is not dilatedf--the spreader or button e will be held firmly to itsseat. When a iiow of water occurs, the water-pressure will lift thespreader 0E its seat and permit water to emerge in a jet. The generalform of this jet under normal pressure is clearly shown in Fig. 3,Where'in the Water-j et is shown as of a general ovoid shape. When theWater-pressure is relieved, the spreader will be restored to its normalposition by the natural resiliency of the diaphragm cl. This spreader byreason of the duties required of it is preferably made heavy. Some kindsof metal will suffice for the purpose. It will be obvious that as theorifice of the irrigator when not in use is kept firmly closed therewill be no chance for lodgement of foreign matter therein, and whateverforeign matter may ,collect at the periphery of the annularemission-orifice will be immediately Washed away when water is runthrough, as is usually done before use.

Having described my invention, what I claim, and desire to secure byLetters lPatent, 1s

l. The combination of the tube,the spreader at the discharge end of thetube, and the elastic cross-piece extending transversely of the tubesbore and secured to the tube peripherally, the spreader being connectedwith the said cross-piece at a distance from its edge,

so that the cross-piece by bending will allow the spreader to uncoverthe outlet of the tube.

2; The combination of the tube,the spreader at the discharge endthereof, and the elastic cross-piece the marginal portion of which issecured to the tube while its central portion, which extends across thetubes bore, is connected with the spreader and apertured adjacentthereto.
